Bill Kendrick writes: Radio magazine has pointed out that as of this month, single-station radio iOS apps are being rejected because Apple considers them "spam" (and apparently specifically compared them to fart apps). Jim Barcus, author of the letter to Radio and president of DJB Radio Apps, finds it ironic that apps cannot mention other mobile platforms (e.g., Android), yet "radio stations have to be forced to have its competitors on the same app."
